Okay, here's some over-all stats relating to deaths in general according to JAMA for 2005:

Tobacco (435,000 deaths; 18.1% of total US deaths)
Poor diet and physical inactivity (400,000 deaths; 16.6%)
Alcohol consumption (85,000 deaths; 3.5%)
Microbial agents (75,000)
Toxic agents (55,000)
Motor vehicle crashes (43,000)(including drunk drivers)
Incidents involving firearms (29,000)
Sexual behaviors (STDs, hepatitis B and C, and cervical cancer) (20,000)
Illicit use of drugs (17,000)

So let's ban alcohol and tobacco too...together they make up almost 1/5th of the total deaths in the United states Far more than the <1-2% that firearms and cars cause. According to the FBI, in 2005 75% of gun deaths were by illegally obtained guns...so banning guns would get rid of 25% of the deaths, of which most of those are likely accidents and suicide...the suicides would still kill themselves anyway and accidents can be lessened by education, but they will always happen.
